IF (because the first things districts gut is art), you can take it or leave it. (the teaching profession)
...
OR art funding gets gutted and you can bump someone to get back into the classroom..

IF you have done art on the cart nonsense before..

IF you are going to an entirely new school..

Yeah, I might do it.

The big if is what does the administration/district expect you to do. I threatened to quit if I didn't get a space because the administration (private school here), wanted studio art instruction. There is no way to do anything other than paper and some sort of dry medium in a 50 minute time slot. 10 minute intro/pass stuff out. 30 minutes to hopefully get something done. 10 minute clean up and get out. The home room teacher is not there, and I have to leave the room how I got it. That meant nothing spilled/goobed/smeared anywhere. No place to store unfinished projects.

I did that for exactly one year and then told them room or else.

My friend does *art education*, and drags the cart around. More like an instruction class for kids at an art museum. She talks about different artists. Color wheel. Properties of light. Perspective. The class may to a tiny bit of hands on stuff, but never true an art project. Think Bill Nye the Science Guy, you have to be that quick and entertaining or else the class will eat you alive. You are basically preparing mini shows for the class. Educational performer (?). I say that because you only have 50 minutes per how many days. You don't have that day in and day out background to build on with the kids.

Classroom management is entirely different. Don't have 15 minutes to burn up with Lil Frequent Flyer. I am not allowed to send them to the office. (short of a desk getting tossed, and me having to clear out the classroom). My room is similar to "What Happens in Vegas, Stays in Vegas." Unless something happened that might spill over to her class. (ODD child was a hot mess before my class, an incident occured and now he is really loaded for bear), I can't whine about how bad the class behaved. It's all on me, which it should be.

Different school, because it just get weird. Easier for me to roll into a new place, than having expectations which are not met on both sides.

Also remember, you may have after school duties which are required. I do school art shows three times a year. Opening night is in the evening. I am required to help out with "anything artsy". Choir needs a banner, I'm there. Banner for school field day. It's me. Something special Principal Skittles wants...yeah..I'm doing it.

I also do grades for 280 kids (around that number). I have to write more than one sentence comments. I also get the lunatic parent who is hacked of S'neuflayke got a P+ instead of an S+. Now I have a meeting with parent, Principal Skittles and me dragging out 3rd grader's portfolio defending that stupid grade. I am required to give two written test per card making too.

Before I would make that jump, especially if I have never done art instruction before, I would want to know EXACTLY what is expected of me. Specials (art, music, PE) isn't easier, just a different skill set.
